Trakio — GPS Lap Timer for Track Days Trakio is a focused lap timing app built for drivers who want clean data and zero distraction on track day. Open the app, select your circuit, and drive — Trakio handles the rest. Pre-Session Checklist Before you head out, Trakio confirms you're ready: GPS signal strength, battery level, and start/finish line configuration. No surprises on your out lap. Auto Circuit Detection Trakio uses your location to automatically identify your nearest circuit and pre-select it for you. Check the weather conditions and wind at the track, then name your session and go. GPS Lap Timing Laps are timed automatically as you cross the start/finish line — no buttons to press while driving. Run it on your iPhone's GPS, or pair a Bluetooth receiver for a faster, sharper data stream. External GPS Support Connect a Qstarz BL-1000GT / BL-818GT or a RaceBox Mini, Mini S or Micro, and Trakio times your laps from a 10-25Hz stream instead of the roughly 1Hz your phone provides. Crossings land where you actually crossed and sector splits hold up. Circuits Around the World Search in English or Japanese, filter by country, sort by what's nearest, and star the ones you run most. Every circuit is drawn with its real outline, so you know a track by its shape. Session Analytics After each session, dive into your data: - Best lap time - Top speed - Lap consistency score - Theoretical best lap (your best sectors combined) - Lap delta trend — see if you were improving or fading - Full lap-by-lap breakdown with gap to your best GPS Trace on Satellite Map Each session shows your smoothed GPS line overlaid on a satellite map of the circuit, with start/finish and sector lines marked. Session History Your session history is stored on-device. Search and filter by all sessions, recent, or your best runs. Rename sessions, log your car, add notes, and track your progress across every visit to every circuit. Global Leaderboard Optional, and entirely up to you. Post a lap to the leaderboard for a circuit and see where it lands against other drivers. Nothing is published unless you choose to share it. Share Your Results Share your session highlights as an Instagram Story — choose a template, add a background photo, and post your best lap straight from the app. Trakio Pro Trakio is free to try with 3 saved sessions. Trakio Pro unlocks unlimited saved sessions, PDF lap time sheets, and CSV lap exports. Available as a yearly auto-renewing subscription or a one-time lifetime purchase. The yearly plan renews automatically unless canceled at least 24 hours before renewal, and is managed in your App Store account. Payment is charged to your Apple Account. Designed for the Track - Dark mode for early morning sessions - Available in English and Japanese - No account required — sessions, laps and notes stay on your device. Only a leaderboard time you choose to share leaves it. Circuit outlines are derived from OpenStreetMap data, © OpenStreetMap contributors, ODbL 1.0.

SEE WHERE YOUR LAP TIME GOES Created by a professional racing driver and instructor. Mount your iPhone, drive your session and get every lap timed, onboard video with telemetry and a corner-by-corner breakdown: where you braked too late and where you lost speed on exit. VIDEO WORTH SHARING Record with iPhone cameras or connect a GoPro. G-Box overlays lap time, speed, G-forces, track map and RPM on your video. Pick a race-car style dash or a vertical layout for social media. On supported iPhones, film both cameras at once: the road and the driver. ALL ON ONE IPHONE 25 Hz Fusion combines the iPhone's GPS and motion sensors to calculate a smooth driving line between GPS fixes, with no external receiver. These are calculated positions, not 25 Hz satellite measurements; results depend on GPS reception and phone mounting. Add a compatible OBD adapter for RPM, estimated gear and power, or an external GPS receiver: G-Box, RaceBox Mini, Mini S and Micro, and selected Dragy models. COMPARE YOUR LAPS • Automatic lap timing, live delta, sectors and predicted lap time • Speed, G-forces, RPM and delta on synchronized graphs and map • Braking, turn-in, apex and exit speed against your best lap • Friction Circle and a theoretical best lap from your strongest sectors • Session replay on 2D and 3D maps YOUR DATA, YOUR WAY Import sessions from RaceChrono, Harry's LapTimer, VBOX, Race Navigator, MoTeC and AiM. Export to GBO, CSV, VBO, GPX and NMEA. TRY IT BEFORE YOUR TRACK DAY Open the included Nürburgring Nordschleife demo lap (8:06) to explore maps, graphs and lap timing before your first session.

Sessions without laps don't count. FREE AND PRO Free: lap timing with iPhone GPS, map and speed graph, session import, OBD logging. G-Box Pro: 25 Hz Fusion, video recording and overlays, lap comparison, all telemetry channels, corner analysis, OBD power and external GPS receivers. Choose a monthly or annual subscription (the annual plan starts with a free month for eligible new subscribers) or a one-time Lifetime purchase. AI analysis uses separate credits.
